A source revealed that the littlest Jo Bro and Miss Universe, Olivia Culpo, were on a date at Ovest Pizzoteca in New York City on Thursday night!

Bellissima!

The eyewitness explains:

"Nick was leaning in towards her across the table like she was saying something really important. They looked really happy when they walked together. Me and my friend both agreed they were, like, swinging their arms all happily."

OMG, this is too cute!

Before dinner, the duo were allegedly spotted outside of Nick's NYC bachelor pad:

"They were holding hands and there were fans standing outside. As soon as they saw the fans, they stopped holding hands."

Aww!

Don't hide new love!

Maybe N should take a page out of the Joe Jonas book of dating and have hand seXXX all over the city with his new lady friend!

Nick met Olivia when he cohosted the 2013 Miss USA pageant, and it looks like this pageant queen might have found her king!
